Abstract

The paper discusses the floristic and coenological structure of the Pannonian part of the Eurasian forest steppe biome. The vegetation of the sand landscapes of the Hungarian lowlands is examined where a climate gradient was detected with decreasing annual precipitation from NW to SE. For studying the effect of the gradient, sites in three different sand landscapes were selected. With increasing aridity, semidesert-like communities become dominant and the steppe grassland, Festucetum wagneri loses almost all of its steppe characteristic. Among the soil factors it is the organic matter content that explains the closed steppe-open grassland trend. The chorological analysis of the forest and steppe grassland species does not support - despite previous expectations - an opposite distributional trend for the two groups.
